A cluster management system and method for synchronizing content libraries within a distributed computer system allows an on-demand synchronization option of a content library subscribed to a publishing content library, which includes at least a consumable software item and metadata of the consumable software item, to be enabled. As a result of the on-demand synchronization option of the subscribed content library being enabled, the metadata of the consumable software item is downloaded from the publishing content library to the subscribed content library without downloading the consumable software item. The consumable software item is downloaded from the publishing content library to the subscribed content library in response to user selection of the consumable software item at the subscribed content library.
